Decide whether you are gonna risk charge/court from the outset and stick to your plan – if you are, argue your version of events all the way to court. But – you need to consider…….
Has the incident been captured on CCTV? Are there any winesses? (independant of both A & B) Are there any other sources of info that could come out at a later stage that would bias a persons assessment
of what actually took place? This will probably determine the eventual outcome in favour of A or B. If it’s purely down to A’s word Vs B’s word, (plus previous convictions etc) then it will come down to who the magistrate believes on the day.
Has person B already been visited by the Police? If not, has person A actually filed a complaint against person B already? Without a complaint there is no case to answer.
